Before the ACA was passed, insurers might have charged someone with depression 50 percent more in premiums than someone without it, and being overweight could have resulted in a 25 percent surcharge. An analysis from AmericanProgress.org outlines how much costlier health plans could be under Trumpcare with a surcharge for pre-existing conditions. Here are just a few examples:

Asthma: 106% surcharge ($4,340)

Autistic disorder: 135% surcharge ($5,510)

Diabetes (uncomplicated): 137% surcharge ($5,600)

Seizure disorders: 179% surcharge ($7,300)

Major depressive and bipolar disorders: 208% surcharge ($8,490)

These figures represent only the surcharge, which would be added to the standard premium for a healthy person. The surcharges listed above don’t include any assistance programs that might be implemented under Trumpcare (though the analysis from American Progress does list adjusted rates). In one extreme example, people with metastatic cancer could face a premium surcharge of 3,500 percent – an extra $142,650 per year for coverage on top of regular premiums and undoubtedly high medical bills.

The AHCA only allows states to charge higher premiums for people with pre-existing conditions if the states set up high-risk pools to offset the cost. Likewise, the federal government is allotting about $130 billion over the next nine years toward a Patient and State Stability Fund. Critics argue that this fund – and other so-called “invisible risk-sharing” methods – isn’t enough to help people with higher premiums afford coverage. The people who need more medical care may not be able to afford it under Trumpcare.

More Common That You Think

You might be thinking, “I don’t have a medical problem, so this doesn’t concern me.” Think again. Kaiser Family Foundation analyzed pre-ACA medical underwriting practices nationwide and determined that about 27 percent of U.S. adults have a condition that would make them uninsurable under the old guidelines. We’ve outlined 25 conditions that could count as “pre-existing” under Trumpcare in a handy infographic, along with how common they are among the U.S. population.

Our infographic doesn’t include every condition that an insurance company might consider “pre-existing.” In fact, it’s not even close.

Under pre-ACA rules, insurance companies could define their own set of standards for medical underwriting. Some insurers set stricter guidelines than others. If you have one of the following conditions or medical problems, then you may be subject to medical underwriting if you let your coverage lapse under Trumpcare:

Even the list above isn’t exhaustive. There are hundreds of conditions that an insurer might use during the medical underwriting process, including sub-conditions or very specific definitions of certain conditions, like cancer. The definition of “pre-existing” could include conditions that you’ve had in the past but don’t currently have. If you’ve ever had the following conditions and/or had difficulty due to the following conditions, then you may also be subject to medical underwriting if you let your coverage lapse under the AHCA:
